Been away for a while - haven't even touched the printer since before xmas.

Michael released his new drives and it started the itch back up again.

Here's the main frame in PLA - probably going to re-do it in PETG. It's pretty strong, but after I finished it I realized I did the last ones in PETG and they have held up great, why mess with a good thing. By offsetting the holes in the cross brackets, Michael made it real easy figuring out which parts go where.

Here are all the drive train pieces, these are all printed in PETG [6 shells (top/bottom/sides) - 30% fill]. The pieces on the left are printed axles - I'll most likely replace these with metal equivalents.

When installing the gears, install the middle one from inside the motor cage - and then move it left/right into position - fought with this one for a bit.

The rest is pretty straight forward.

I printed the tire with Ninjaflex Cheetah [ 3 shells - 20% infill ] - the lower infill gives the tire a little bit of flex. I lubed the edge of wheel with some Super Lube and positioned the tire on as far as I could by hand - a couple whacks with a rubber mallet and it popped right on - MUCH easier than V2.

Still waiting for some hardware and I still need to print the upper part of the assembly (ankle) before putting it together to test it out.
